Hi,
I am not a developer, but I do know (loosely) what events these refer to:
* lease4_recover (Kea has removed the lease from the lease database
(post expire or release) things like lease affinity affect when this
happens)
* lease4_release (client sent a DHCPRELEASE packet)
* lease4_decline (client sent a DHCPDECLINE packet)
Thank you,
Darren Ankney
